SPECIFICATION forming part of Letters Patent No. 608,388, dated August2, 1898.

I Application inea August 20,189'11.

To @ZZ whom t may concern.-

Be it known that I, WALTER BROWN, a citizen of the United States,residing at Cresce, in the county 0f Howard and State of Iowa,

have invented certain new and useful Im-I provements in Gasolene-Stoves;and I do declare the following to be a full, clear, and expertains tomake and use the Same.

This invention relates to improvements in n gasolene-stoves, and thenovelty and many advantages will appear fromthe following vdeo scriptionand claims when taken in connection with the annexed drawings, in which-Figure 1 is a vertical longitudinal sectional view of my improved stovewith a part of the `support broken away. Fig. 2 is a cross-sectionalview, taken in the plane indicated by the dotted line of Fig.v1,'with apart of the top plate broken away andthe supports removed.- Fig. 3 is aperspective sectional detail view illustrating the shelf, the vaporizingchamber, and the gas and air fines; and Fig. 4 is a perspective view ofthe absorbent pad and its holder with parts broken.

Referring by letter to said drawings, A indicates the topjplate of astove, which may be that of an ordinary gasolene-stove, and while hereshown as ofthe single-burner type it is obvious that any suitablevnumberof burners might be-employed. This top is supported on suitable legsctor other supports, as the stovetop and supporting means form noessential parts of 4my invention.` .Arranged at the rear or one sideofthe stove-top is a horizontal shelf B. This shelf'may be composed ofgalvanized iron or other suitable material and may have a verticalflange bV on one end wall and both sides, so as to receive and seat thevaporizing-chamber C and the absorbent arranged therein. This shelf maybe suitably4 braced in position, such as by means of arms c, which mayrest on the stove-top or be otherwise connected with the stove-support.Depending from the shelf B and at its forward end is a'gas-feed tube D.This feed-tube has a horizontal branch d, which passes beneath thestove-top to a suitable distance and'may be secured in position by abracket el The upper end of the vertical branch of the tube D may havethe shelf B formed integral there- Serial No. 648,957. (No model.)

with or rigidly fixed thereto and is of a peculiar construction, havingits rear wall carried inwardly, as shown at f, so as to contract thethroat thereof, and its opposite or forward wall is carried to a greateraltitude than'the rear inwardly-directed wall, as at h, and better shownin Fig. 3 of the drawings. This gas-feed tube, which is of an elongatedrectangular form in cross-section, by preference isprovided at asuitable altitude with lateral holes t', which are designed to furnishpassages for air, and the tube is flared by carrying its side wallsoutwardly and upwardly, as shown at j and 7c. It will be observed thatby extending the walls as shown at 7o a stop will be formed for theslidable pad-holder, as will be presently described.

The vertical branch of the gas-feed tube D is provided with a slidablecollar E, which is designed to regulate and close the inward draft.

F indicates a burner which may be mainly of the ordinary construction.This burner is connected with the horizontal branch of the gas-feed bymeans-of a drum g, which is placed over an aperture Z in the horizontalbranch "d, and this drum passes through and is disconnected from theinterior of a horizontal branch 'm of the hot-air tube, so that any gaswhich may pass from the feed-tube will not enter the hot-air tube. Y

G indicates the hot-air.v tube, which comprises a vertical branchV and ahorizontal branch, as shown.v This tube is open at both ends and haspassing through it the drum g. Depending from the burner-head andsurrounding the upper part v of the drum is a brass ring I, whichextends into the horizontal branch of the hot-air tube. The drum ispreferably composed of tin or other slow con- `ductorvof heat, while thering I is composed of brass or material of a high conductive nature. Bythis means the ring will extract the heat from the burner and conduct itinto the hori' zontal branch of the hot-air tube, when the air enteringthe lowerrend of said tube will absorb the heat and carry the sameupwardly in the course indicated by the arrows.

The vaporizing-chamber C may be of a general rectangular form, as shown,so as to rest upon the shelf B. This chamber is open at its forward endto' receive the absorbent- IOO holder J, which is designed to slidetherein. The absorbent K may be composed of any suitable material whichwill absorb or take up the gasolene, and it is so Vfixed in the holderas to extend from side to side thereof and snugly against the front walln, but leave a passage p above, a passage r/V, and another passage rbelow, so that the air entering the vaporizi11g-chamber will be directedover and around the entire surface of the absorbent. The chamber C isprovided on its top at its forward cud with a hinged hood or dedectorIl, which is designed to extend over the vertical plane of the hot-airtube, so as to defleet such hot air as may be received therefrom intothe vaporizing-chamber, so that such air may become mingled with andabsorb the gases and be carried back and down through the courseindicated by the arrows and to the burner to be consumed.

The absorbent-holder .I is provided externally on its front wall with asuitable handle, whereby it may be carried to a suitable can to besaturated with gasolene, and below this handle I provide a transversstrip s, which is designed to overlap the upper edge L of the gas-feedtube. ily the employment of this strip it will be seen that the throatof the gasfeed tube may be regulated so as to govern the passage of gasfrom the vaporizing-chamber to the burner. It will be seen that bysliding the absorbent-holder inwardly from the position shown in Fig. lthe passage may be closed to any desired extent. This is very desirablein shutting out the flame or burner. for the reason that the passagewill not be entirely closed when the flame is shut out. If the throat ofthe gastube should be entirely closed by sliding the absorbent-holderinwardly, the llame would be shut out before the gas in said tube wouldhave time to descend and be consumed, while by leaving a slight openingthere will be snflicient downdraft to entirely consume all of the gas inthe feedtube before cutting off the llame.

ly the employment ofthe collar E it will be seen that more or less airmaybe adm itted into the gasolene-tube,and when there is sufficient airadmitted through the hot-air tube the collar may be moved to entirelyclose the aperture in the gas-tube. The defieetor L may have a curvedtop, so as to serve more effectively in directing the hot-air currents.

lVith a stove constructed as described the danger of spilling or leakageof the `gasolene is reduced toa minimum and there is no danger ofexplosion.

lVhile I have shown and described my preferred construction, yet I donot wish to be understood as limiting myself.` to the details which Ihave set up, as it is obvious that many of the parts can be alteredwithout departing from the spirit of my invention. The tubes may in somecases be made round, the slidable collar may be altered so as to use adra ftregulator of other type, and the absorbent may be of any pervionsmaterial.

lIaving thus described my invention, what I claim is l. In a gas orvaporstove, the combination of a vaporizing-chamber, a burner, agas-feed tube connecting the vaporizing-ehamber and the burner, and aslidable absorbent-holder arranged in the vaporizing-chamber andcontrolling communication between the said chamber and the gas-feed tubeand consequently the quantity of gas supplied to the burner,substantially as specified.

2. The combination with a suitable burner and a vaporizing-chamber5 of agas-.feed tube having the upper end of its rear wall directed inwardlyand its front and side walls carried above the rear wall, and a slidableabsorbentholder adapted to move over the mouth ofthe feed-tube so as toregulate the feed, substantially as specified.

3. In a gas or vapor stove, the combination of a vaporizi11g-chamber, aburner, a gas-feed tube connecting the vaporiziiig-chamber and theburner, and a slidable absorbent-holder arranged in thevaporizing-ehamber and controlling communication between the saidchamber and the gas-feed tube and consequently the quantity of gassupplied to the burner; the said absorbent-holder being provided with aportion adapted to close the feed-tube to the atmosphere whencommunication between the said tube and the vaporizing-chamber ispartially closed and also adapted,when the feed-tube is entirely closedto the vaporizing-ehamber, to assume such a position as to establishcommunication between the feed-tube and the atmosphere, substantially asspecified.

i. The combination witha suitable burner; of a vaporizi11g-chamber opento the atmosphere, a gas-feed tube, a hot-air tube open at both ends tothe atmosphere,and a hood adapted to direct the hot-air currents intothe vaporizing-chamber, substantially as specified.

In a gas orvaporstove, the combination of a vaporizing-chamber open atone end to the atmosphere and provided above such open end withadeflector, a burner, a gas-feed tube connecting the vaporizing-chamberand the burner, an air-tube arranged to receive the heat of radiationfrom the burner and discharge the same against the dellector, and aremovable, slidable absorbent -holder arranged in the vaporizing-chamberand controlling communicatien between the said chamber and the gas-feedtube; said absorbent -holder being provided with a portion adapted toclose the feed-tube to the atmosphere when communication between thesaid tube and the vaporizing-ehamber is partially closed and alsoadapted, when the feed-tube is entirely closed to thevaporizing-chamber, to assume such a position as to establishcommunication between the feed-tube and the atmosphere, substantially asspeciled.
